Piovan has redeveloped its range of granulators for the plastics industry and has launched a new range of small, medium and large granulators, characterised by innovative technical and design-based features.
Piovan says the granulators are a “step ahead” of current versions available in the market and are fitted with a unique tangential cutting system. The rotary blades are inclined and are positioned as close as possible to the geometric tangent of the cutting circle, therefore optimising and improving cutting precision. In this way, Piovan says high production capacities are achieved using smaller motors, with the additional benefit of minimising dust production and heat generation. These features ensure a more regular cut and more dimensionally consistent regrind. Without a cutting chamber of this quality, the regrind, in addition to being irregular, will also have a higher dust content and will therefore be more difficult to process. The cutting chamber is made from machined pieces, which are then assembled rather than being cast or welded. This design has enabled the construction of high-precision components that improve the efficiency of the cut and the quality of the ground product, while improving the life of the granulator, as worn pieces can be replaced.
Another distinctive feature of Piovan granulators, says the company, is the ability to customise. Even the most basic versions can be modified to suit the specific needs of the process (e.g. blow moulding, extrusion, injection) and to comply with specific customer requests in terms of space, granulator loading and unloading requirements and protection of the operating environment - these machines also guarantee extremely low noise levels.
